Toughpower GF1 1200W Gold - TT Premium Edition The fully modular Toughpower GF1 series now comes in 1200W and built to deliver 80 PLUS Gold efficiency. The series features a 140mm hydraulic bearing fan, Japanese capacitors and other premium components to help deliver a continuous and stable power with an ambient temperature up to 50°C, while near silent operation and reliable performance are guaranteed. Zero Cable Platform Farewell to messy cables! Ultra Quiet 140mm Hydraulic Bearing Fan Featuring a 140mm hydraulic bearing fan with intelligent RPM controls to help guarantee superior cooling performance and near silent operation. Smart Zero Fan Designed with our Smart Zero Fan, the fan will not spin until the load exceeds 30% of the power supply, minimizing the fan noise. ＜30mV Low Ripple Noise All ripples are lower than 30mV on +12V, +5V or +3.3V from 0% to 100% load to ensure a stable operation and keep your performance-critical components to function reliably for longer. Extremely Strict Voltage Regulation ＜±2% The voltage regulation, more strict than Intel’s standard ±5% for major rails and ±10% for -12V, is set to no more than ±2% for major rails to meet the highest performance. Fully Modular Low-Profile Flat Cable Offers cable selection for users while powering the system at an advantageous voltage. Low-profile flat black cable makes cable management easier, reduces clutter and increases airflow inside the chassis. Premium Japanese 105°C/221°F Capacitors Providing great durability as well as offering the highest stability, while remaining reliable. High Amperage Single +12V Rail Powerful single +12V rail ensures a stable and reliable supply to other PC components.
